Should I buy a new build because of the negative gearing changes?

Published 26 June 2026 · Last updated 19 August 2026

Quick Answer

The legislated changes to negative gearing apply differently to new builds — new properties retain access to negative gearing even after the rules change, making them comparatively more attractive.

New builds and negative gearing policy changes

A key design feature of the legislated negative gearing changes is that new residential properties — new builds — continue to qualify for negative gearing even after the rules change for established properties from 1 July 2027. This is seen as a way to encourage housing construction while reducing speculative demand for existing stock.

How new builds are expected to be treated

Under reported proposals:

  • Established (existing) residential properties purchased after the commencement date may no longer generate negative gearing losses that can offset other income
  • New residential properties (newly constructed dwellings) are expected to retain access to negative gearing under current rules
If this design is enacted, investors who want the tax benefit of negative gearing after the commencement date would need to buy new rather than established.

Additional tax advantages of new builds

Beyond the negative gearing question, new builds already offer superior depreciation:

  • Full Division 43 capital works (2.5% on the full construction cost)
  • Full Division 40 plant and equipment (no second-hand asset restriction)
  • Often higher overall depreciation deductions than established properties of the same value
This means new builds are doubly attractive under the legislated changes: they retain negative gearing and they generate more depreciation.

The downsides of new builds

Tax benefits should not override fundamental investment considerations:

  • New builds sometimes carry a premium over established property for comparable locations
  • Some new developments — especially high-density apartments — have faced issues with oversupply and lower capital growth
  • Depreciation benefits diminish over time as the building ages

A balanced view

If you were already considering a new build as a sound investment in a good location, the proposed tax changes make the case stronger. If you are switching from an established property to a new build purely to preserve a tax benefit, make sure the underlying property fundamentals support the decision.

The interaction of negative gearing rules, CGT changes, and depreciation on new builds is complex. A tax advisor and a quantity surveyor can model the after-tax returns for your specific situation.

Frequently Asked Questions

Is the new build exemption confirmed?

Yes. Under the legislated changes, new builds remain eligible for negative gearing while established residential property acquired after Budget night is ring-fenced from 1 July 2027.

What counts as a "new build" for these purposes?

This is one of the details yet to be finalised. It is likely to mean a newly constructed dwelling being purchased for the first time from a developer or builder — but the precise definition will be in the legislation.

Do new builds generate more depreciation than established properties?

Generally yes. New builds qualify for full Division 40 and Division 43 depreciation, whereas established properties purchased after 9 May 2017 face restrictions on plant and equipment claims.
